Portable Particle Counter Model 9350 & 9550

Product Enquiry

The TSI AEROTRAK 9350 & 9550 Portable Particle Counter offers the most features and flexibility for customers interested in manually monitoring particle contamination at high flow rates. These particle counters can be used as stand-alone portable counters or can be integrated into a facility monitoring system. Both models offer a compact light weight ergonomic design for ease of use. The 5.7 inch high contrast colour touch screen interface makes these instruments easy to operate and facilitates viewing data from a greater distance. These particle counters can also store up to 10, 000 sample records which can be conveniently downloaded using USB, Ethernet (TCP/ IP) port or printed directly via its built-in printer. 

The instrument reports up to 6 particle sizes simultaneously and includes an internal alarm. 

Backed with a standard 2 year warranty and TSI commitment for superior service and support, there is no other portable particle counter on the market today with such features and benefits.
